JOHN F. CARPIVIILL, OF NEW BRITAIN, CONNECTICUT BUCKLE.

Application filed. January 12, 1921. Serial No. 436,782.

To all whom it may concern Be it known that I, JOHN F. GARPMILL, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Buckles, of which the following is a specification. 7

This invention relates to buckles. A buckle involving the invention may be used in many different fields. It may be employed with utility for holding a strap or webbing in closed position when associated for instance with a belt, for holding school books or in harness. From this it will be clear that I am not restricted to theuse of the buckle in any particular field. Ihave a number of objects in view among the principal of them being the provision of a'buckle which can be inexpensively produced, which is strong and thus serviceable, and which effectually holds a strap, band or webbing in closed condition but which may be. quickly and easily released. The device comprises other features of novelty and advantage which with the foregoing will be set forth at length in the;

following description j-where-in I will describe in detail several ofthe many forms of.

embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification. Clearly I am not restricted to this showing. I may depart therefrom in a number of respects within the scope of the invention defined by the claims following said description.

Referrlng to sald drawmgs: V Flgure 1 is a perspectlve vlew of a buckle involving my invention showing the same associated with a belt, and portions of which however are only shown.

Specification of Letters Patent.

mama May a, 1921.

Desirably the buckle involves in its makeup a body member, a locker and a terminal member such as deslgnated 111 a general way respectively by 2, 3 and 4. The body member2 comprises a bottom as 5 having eo extenslve therewith at opposite sides there of, the parallel fianges6 both of which may as shown be on a longitudinal and com paratively slight curve, the forward portion of the side'flanges 6 being deeper than. at

the rear portion thereof and for approximately half the length of the respective flanges to thus provide bearing portions to support whennecessary the locker 3 and the terminal member 4. The bodymember thus far described is usually of sheet metal although it may be cast or formed in any other preferred manner, and its outer surface or what is shown for instance in Fig. 3 'asthe side flanges 6 as'probably shown best in 1. The studs fit the holes somewhatfreely and are generally integral with the terminal under surface of the bottom 5 may be en- 7-adapted to enter transversely alined holes or perforations 8 inthe deep portions of the member 4 although this may not be necessary 1n all cases, for as w ll be understood the invention involves certain broad relations".

The outer portion of the terminal member 4 is provided with parallel lipsor cheeks'9 having as shown holes, or perforations 10 near the outerv corners and in register with volves two branches at right angles to each other, the studs 11 extending therefrom practically at the junction .of the branches.

The'short. or inner branch of the detent is toothed as is common to enter the adjacent end portion of the. web 13 the lateral edges of 1 which are against the lips or cheeks 9. When the detent 12 is closed as shown'particularly by full-lines in'Fig: 3, the web 13 will be securely connected with the terminal member 4.

. The lockershown is denoted by 3 and moved to locking and releasing positions through'the agency of the terminal member pivotal mount for the locker, the pivots or studs 14 however being nearer the bottom 5 than the pivots or studs 7 although this is not an essential point. The locker 3 at its free end is rounded or bulged as at 16, this rounded or bulged portion being adapted to press the free end part of the web 13 against the bottom 5 of the body member 2 as shown for instance by full lines in Fig. 3. The terminal member 4 is shown as having at its inner end the transverse flange or lip 17 at ap proximately right angles thereto which is shown as having practically centrally of the lower edge thereof, the lug 18 adapted to enter the slot 19 .of thelockor 3. The back wall of the slot 19 has an angular lug or hook20. a

In Fig. 3 the dotted lines show the buckle as in the open position, so that the free end of the belt or web 13 can be slipped through the space between the locker 3 and bottom 5, the opposite end of the belt being connected as I have already set forth to the terminal member 3. It will be clear that when this terminal member is pressed down or'in from the dotted or open position in Fig. 3 toward the full line or closed position-as shown by the full lines in the view, the flange 17 acts on the locker 4 and causes the latter, to

impinge or bind the web or belt 13 firmly' from the full line to the dotted line position in Fig. 3 and at this time the lug 18 will engage under thefree branch of the angular lug 20 so as'to lift the inner .or forward portion ofthe locker 3 clear of the belt to free the same from the clamping .efl'ectof said locker. .I-have'noted'the fact that the locker 3 at its free end is rounded or bulged as at 16,

' thislocker being pivotally mounted as at 14.

By reason of the construction the locker between itscenter of motion and free end por tion is permitted toyield or is resilient in order to give a little spring tension on a belt of leather or other such substance. This is an important feature in that the locker can obtain a proper hold upon the belt.

In Fig. .4 the construction is very much like that in Figs. 1, 2 and 3. In point of fact the only difference really is that the locker 3 is pivotally mounted at 3 at its rear edge between the side flanges 6.

In Fig. 5 show another modification. In this construction the body of the buckle is denoted by 25 and it is just like the body 2 or 2. Between its side flanges is pivotally mounted the locker 26 which functions against the belt. This locker has at its inner end the depending flange or lip' 27 which binds the belt against the bottom 28 of the body 25.

In Fig. 6 I show a further modification. This view illustrates a locker 30 which functions like the lockers 3, 3 and 26. Its free portion has a bulge31 furnished with longitudinal lips 32 by which a grip can be had upon the belt in certain cases, although a plain bulge or cam portion as 3 and 16' already described functions properly.

In Fig. 7 the modification there shown is in the terminal member. Theonly difference between this terminal member denoted by 10 and the other hereinbefore described, is the way the web A2 is connected therewith.

In this construction saidterminal member.

4C0 has at its free or outer end a loop 41 and held in place by stitching.

WVhat I claim is:

1. A buckle comprising a body having a bottom and side flanges, a terminal member pivotally mounted between the side flanges and to which a web may be connected, a locker pivoted between said flanges, the terminal member having a depending flange furnished with a lug andthe locker having a slot to receive the lug whereby upon lifting of. the terminal member the lug will act to lift the locker, the flanges of the terminal member acting against the locker when the terminal member is swung down to set the locker 1nto engagement with the web under the locker.

2. A buckle comprising a body havinga bottom and side flanges, a terminal member;

member acting against the locker whenthe terminal member is swung down to set thev locker into engagement with the web, under the locker, the lockerbeing resilient between its center of motion and its free end.

3. A buckle comprising a, body having a 1 20 ingof the terminal member the lug willact to lift the locker, the flange of theterminal bottom and side flanges, a terminal member pivotally mounted between the side flanges and to which a web may be connected, and a locker pivoted between the side flanges and between the first mentioned pivot and the bottom of the body, the terminal member having means to positively move the locker into web-clamping position, the terminal member being also connected with the locker to positively move it into web-releasing po- 10 sition. I

In testimony whereof I affix m signature.
